How to Install Replacement Vinyl Windows

If you are a homeowner looking for a way to save money on your monthly energy bill, you should think about replacing your old windows with vinyl replacement windows. These windows can be custom made to fit any window in your home. You don’t have to hire a professional to install these, as you can learn how to install replacement vinyl windows yourself.  

Supplies

• Pry Bar


• Sharp Knife


• Vinyl Replacement Windows


• Carpenter’s Square


• Wood Blocks


• Saw


• Hammer


• Nails


• Screwdriver


• Caulking Gun with Caulk

 Installation

1. Remove the existing window sash by using the pry bar to take out the inside stops that hold the inner sash in position. Do not damage the stops as you pry them off, as these can be reused. The outside stop is not removable, so do not pry it off. 


2. Cut the sash ropes with the knife and remove the bottom sash. Pry out the blind stop, remove it and pull out the top sash. 


3. Place the vinyl replacement window in the opening. Make sure the window is snug between the stool on the inside and the stops on the outside. Nail a piece of wood to the jamb for a snug fit if the vinyl replacement window is not as wide as the previous window. 


4. Place the carpenter’s square on the window to make sure it is square. If the window is square, skip the next step. If it isn’t square, follow the next step to shim the window. 


5. Saw a block of wood in the size needed to square up the window. Place the piece in the correct position and use the hammer and nails to nail the shim in place.  


6. Screw the window in position through the jambs on the side and replace the inside stop. 


7. Open and shut the window to make sure it operates correctly. 


8. Seal the window on the outside by placing a thin bead of caulk around the entire window.
